Summary

Due to the volatile photovoltaic market in the State of Israel since the beginning of the first arrangements, the unique engineering required for the design, construction and maintenance of photovoltaic systems has not developed a significant awareness among the country's electrical engineers. Due to the common concept of "EPC" which gives the contractor the right to design the system he builds, sometimes the lack of concept of quality assurance in general in the construction industries in the country and instability in regulation, no expertise has developed in this area.

​

This workshop highlights the important issues in the design, construction and maintenance of photovoltaic systems connected to the low-voltage distribution network and intermediate voltage according to the accumulated experience from the first series in the State of Israel, activity in international committees and large projects around the world.

​

introduction

Mike Green will give an overview of the various roles that an electrical engineer should play in the life cycle of a solar power plant, from the design phase including connection to the power grid at different voltage levels, emphases on monitoring design, and other important matters to generalize technical specifications, to handling customer complaints. To the customer

​

Handling of the power factor in photovoltaic systems connected to the network:

Zohar Weinbaum will explain how the facility can be designed so that a solution is obtained for correcting the power factor in all work situations and without deteriorating the quality of electricity in the facility.

​

When producing solar with an emphasis on a net meter arrangement, the consumer will consume the active power that his solar system produces and the rack power he will draw from the grid. Converters manufacturers usually make it possible to control the angle between the voltage and current generated, which makes it possible to produce a maximum active power of a given size of a converter whose size is defined according to its imaginary power.

​

Understanding the meaning of photovoltaic imaging:

Edward Rabin will explain how a photovoltaic energy expert works with solar field imaging software and the significance of various situations affecting system output. Photovoltaic energy is decreasing its production cost compared to the cost of producing fossil energy, which requires maximum production efficiency. The efficiency of a photovoltaic system is determined when planning the location of the panels, their division into strings and converters. We are in an age where every percentage missed at the planning stage greatly affects profitability and fault identification and treatment.
